Title:
APPARATUS AND METHOD FOR MEASURING STREAM WATER LEVEL IN REAL TIME BY USING POSITIONING DATA FILTERING
Document Type and Number:
WIPO Patent Application WO/2020/101102
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and a method for measuring a stream water level in real time by using positioning data filtering, the apparatus and the method filtering out stream water level measurement data so as to guarantee the reliability of measured water level data even when applied to a small stream having a small basin area and a steep slope, and the apparatus comprises: a measurement unit for measuring the water level of a stream to be measured; a positioning data filtering unit using a local linear regression-based bivariate scatter plot smoothing technique through a flexible bandwidth application so as to filter out the water level data measured by the measurement means; and a water level calculation unit using positioning data, which is filtered out by the positioning data filtering unit so as to have a minimized water level measurement uncertainty, thereby calculating the water level of the stream to be measured.
